Precautions
On safety
Should any solid object or liquid fall into
the cabinet, unplug the receiver and have it
checked by qualified personnel before
operating it any further.
On power sources
• Before operating the receiver, check that
the operating voltage is identical with
your local power supply.
The operating voltage is indicated on the
nameplate on the back of the receiver.
• The unit is not disconnected from the AC
power source (mains) as long as it is
connected to the wall outlet, even if the
unit itself has been turned off.
• If you are not going to use the receiver for
a long time, be sure to disconnect the
receiver from the wall outlet. To
disconnect the AC power cord (mains
lead), grasp the plug itself; never pull the
cord.
• (USA and Canada models only)
One blade of the plug is wider than the
other for the purpose of safety and will fit
into the wall outlet only one way. If you
are unable to insert the plug fully into the
outlet, contact your dealer.
• The AC power cord (mains lead) must be
changed only at a qualified service shop.
On heat buildup
Although the receiver heats up during
operation, this is not a malfunction. If you
continuously use this receiver at a large
volume, the cabinet temperature of the top,
side and bottom rises considerably. To
avoid burning yourself, do not touch the
cabinet.
